used to align holes of beams with columns. It is made from a steel alloy, and it has a gradual taper to easily align bolt holes on beams. The bolt bag is a heavy canvas bag used for storing bolts and nuts that erect a structure. A sleever bar is a steel alloy bar used to pry on beams to put them in place, when a spud wrench is insufficient. A beater is forged steel head mallet with a lacquered hickory handle for beating a tapered pin or bull pin into the bolt hole to align the others at the beam end or "point" and stuff the rest of the holes. Drift pins have a tapper on both ends and get to be the largest diameter in the center and are used for aligning holes made up of multiple plates.
352:. The pliers cuts soft annealed rebar tie wire and twist the wire into place. The pliers have a hook bend handle, and a spring in between the handles for self-opening of the pliers. The pliers cut ACSR, screws, nails and most hardened wires. Also, the pliers are finished with a black oxide paint to resist rust on the tool. A tie wire reel is a lightweight aluminum alloy mechanism used for dispensing tie wire efficiently. A rod buster bag is a split-leather double bottom pouch used for holding tools while they are not in use. A rebar hook is a hook made of solid steel that has a snap hook in front, and fits onto a tool belt easily.
337:, works with reinforcing bars to make structures based on a certain design. Reinforcing ironworkers assemble structures with reinforcing bars by tying the bars together with tie wire. They place the rebar inside of forms, so concrete can be poured over top of them to form a solid structure. When reinforcing floors, concrete blocks are used to raise the rebar off of the deck, so no rebar can be seen underneath of the deck of the floor after the forms are stripped. In addition, ironworkers often have to cut the steel that they have for a job to fit into certain positions. For example, the rebar will have to be cut with a
